Re it known ch-atv7 Pinna vrSinnenand (il nien ll. DEAN; y ns of fthe United States, residing; atfdcranton, in-fthe county ol Lack-awarrna andl -ita'te oft lennsylvania, have Ainvented certain new and use'liul 'Iniprovenients in Railroad Rails, et which tie following is a specification.

This invention relates "to an limproved railroad rail and see rs, antoine` other objectsto provide a rail which will bepr-actically -eontinuous and wherein the luse of vfishy `plates will Abe eliminated. Y

The invention seeks, asa further object, to provide a rail embodying mating sections `assrnnblecl in .such manner -Atlntt the joints between the sections wifll be staggered so that each joint will be 'l-iridged i1oy .an overlapping' rail section.

The 4invention seeks, as another object, to providea rail eniloodyinir novel ineans to accon'unodate expansion vand contraction of the rail and wherein ainple and .eiiective provvision will be made for permitting` 4such Lexpansion andeontraction.

And the yinvention seeks, as a still'iurther object, to provide a rail whcrein-should the rail treadbeeoine fractured, the ltread por- Ation rot Vthe rail will, nevertheless, be .'e'ttectually sustained to support ythe rolling `stock and wrecks which would otherwisexbe caused by rail iracture thus obviated.

`Other and .incidental :objects will appear hereinatter.

Figure l .is la wel .of Figure 1, the arrows,

Figure 5 is a. sectional view showinga slight modification, and

Figure 6 is a sectional view showing` a lfurther slight modification.

In carrying the invention into effect, the improved rail is formed of mating sections comprising a base section 10 and a coacting head section .11, the sections being of any approved length. As best broughtout in Figure l of the drawings, the base section 10 is provided with base 'flanges 12 and rising` from said section are spaced parallel web sectional view on the line looking in the direction of plates 18. These web uplaftesare preferably rov.ided with Hat inner and Aouter faces .and at `their inner lower ymargins areL equally thielned `.to-define a reduced medialsocket channel 11i Ilyingl midway between the plates. "llhe headsection is `formed with the usual tread or ball and depending therefronris .a

medial web 15. rllhis webyis also preferably f provided with dat parallel sides andfio-rmed on=the rside faces of the webnea'rlthe. junction thereof with the vtread are roundedrcontraction and erpansionibeads 16 extending -t-roni end to endi-of the web.

In assembling thearaih .a number of the base sections l1'() are, :as shown in Figure 1V7 laid dowvn Aend ito end when Ethe `head sections 11 are itted end to end :in the base sections-and, .as will be observedVt-he joints between the? head sections are staggered with respect 'to` .the joints :between the .ib ase vsections so that practically .a continnousrail is p1ioduced, the `jointsbetween.;,the yheadsectirfins being bridged byfthebasevseetions anc'lfviee versa. As Ibrought out in Figure 4,.'-theiwebs 1.5 ol :the Ahead sections are l#formed tosnugly `fit ,at @their-lower margins ingthe socket channels 14: 'oil the basesections while the beads 116 :are of la radiusfto abut .the Hat in- Anerfaces of the Y.web plates `13 :solthat the webs 1' `will thus .be rigidly supported againstliter-.al movement. Funtherniore, as will be noted, the upper edgesvof the web plates-are "inclined to :seat flatfagainst the lower faces ofthe treadsioi the head sections at opposite sides of the `webs 1,5 for rigidly supporting theitrearls as well `as providing Yclosed joints lbetween said plates and the treals to exclude moisture. Formedin the webs yoffthe head sections suitably :spaced points longitudinally thereof .are

openings 17 ,and A-ornied ,in the web plates ,lotathelbase sections to register with said openings `areslots 18, theopenings and, said slots accommodating bolts 19 rigidly'binding the sections together.

Attention is now directed to the fact that the side walls of the socket channels 14 of the base-sections serve to provide beads of reduced area, as compared with the area ot the inner faces ot the web plates, to contact the webs 15 and, likewise, thebeads 16 have a similarly reduced area ol contactv with saiclplates. The rictional drag between said plates Vand the webs is thus reduced to such extent that the tread sections will, without buckling, be permitted to inove upon the base sections and vice versa under expansion and contraction of the rail and, of course, the slots 18 are provided in the web plates of the base sections to accommodate such movement.

In Figure of the drawings, we have illustrated a slight modification of the invention wherein we employ a base section 20 and a mating head section 21. The base section is formed with a socket channel 22 corresponding to the channel 14 as previously described, and rising from the base section is a web plate 28. Cooperating with said plate to receive theweb 24 of the head section is a web plate 25 having an eXpansion and contraction bead 26 to abut said web and extending through said plates and through the web 24 are bolts 27 vsecuring the parts together. Thus, the plate 25 will be rioidly'held upon the base section while said plate may be removed to facilitate assembling or disassembling of the rail. Otherwise, this modified structure is iden- Iticalwith the embodiment of the invention first described.

In Figure 6 of the drawings, we have illustrated a still further modification of the invention wherein we employ a base secvtion 28 and a mating head section 29. In the present instance, the base section is provided with a medial upstanding web 30 on the sides of which are formed pairs of expansion and contraction `beads lwhile the head section is provided with depending web plates 32 fitting over the web to rest at their lower edges upon the shoulders 33 of the base section. The head section is further provided with a socket channel 84 snugly accommodating the upper margin of the web 30, this channel corresponding to the channel 14 as first described, while the beads 31 bear against the inne'i' sides of the plates 32 for rigidly supporting the head section against lateral movement. Extending through said plates and the web 30 are bolts 35 securing the parts together. Thus, as will be seen, this modified structure comprehends a reversal of the web and web plates asA compared with the embodiment of the invention first described, and in thus reversing the positions of lthese parts, the

possibility7 of moisture being confined within the rail is obviated. i

Having thus described the invention, what is claimed as new is:

1. A railroadV rail including companion alined base sections, companion alined head sections supported yby the base sections, in mating relation and having the joints therebetweenstaggered with respect to the joints between the base sections, the head and base sections being provided one with web plates as well as with a reduced channel between the base portions of said plates and the other with a web accommodated between said plates in spaced relation thereto fitting `in said channel, and expansion beads carried by said web to bear between said plates.

2..A railroad rail including companion alined base sections, companion alined head sections supported by the base sections in mating relation and having the joints therebetween staggered with respect to the joints between the base sections, the head and base sections being provided one with a web and the other with web plates accommodating said web therebetween in spaced relation, and expansion beads carried by said web to bear ybetween said plates, said base sections being further provided between the lower portions of said plates with reduced channels snugly receiving the free edge margins of-said webs.

3. A railroad rail including companion alined base sections, companion alined head sections supported by the base sections in mating relation and having the joints therebetween staggered with respect to the joints between the base sections, the head and base sections being provided one with a web and the other with web plates accommodating said web therebetween in spaced relation and thickened at their lower portions to define a reduced channel snugly receiving the free edge margins of the said webs, and expansion beads carried by said webs to bear between said plates.

In testimony whereof we affixed our 'signatures.
